Reference no: EM13184337

A 0.1019g portion of an aspirin tablet was dissolved in sufficient water to prepare 1.000L of solution. A pipet was used to transfer 10 mL of the solution to a 100 mL volumetric flask. A 2 mL portion of 4 M NaOH (aq) was added to the flask, and the resulting solution was diluted to the mark with water. The fluorescence of the diluted sample solution was found, by the working curve method, to correspond to a salicylate ion concentration of 4.80 x 10^-5 M. Calculate the % acetylsalicylic acid in the aspirin tablet.
